Every call here is based on what the last few years of weather usuallydid in a given month — not what the sky will do on your specific dates. A “GO” month can still hand you a rainy week, and a “SKIP” month can surprise you. Use it to pick when to go, then check a real forecast as your trip gets close.

Nothing here should be your last word before going in the ocean, out on a boat, or up a trail. Surf, currents, and mountain weather change fast and aren’t in this data. Check the National Weather Service, lifeguard flags, and a marine forecast before anything conditions-dependent.

Maui isn’t one weather. Each activity is scored at a single representative spot, so treat the call as the regional pattern — your exact cove, valley, or resort can differ. More on that in how it works.

What counts as “warm enough” or “calm enough” is my opinion as a former travel PM, shown openly so you can disagree. Whale-season numbers are likelihood estimates, not counted sightings.

There are no affiliate or sponsored links on the site right now. If that ever changes, I’ll say so clearly, and it won’t change the calls — an honest read is the whole point.
